Final Assembly
The picture below shows the final configuration. Note that the PCB does not match exactly with the mounting locations of the plastic enclosure so I had to use an intermediate laser cut acrylic plate to screw to the enclosure, and then standoffs and screws to attach the PCB to that board. Holes have been drilled in the bottom of the enclosure to allow 24VAC wire and sprinkler control wires entry/egress. Cable glands that can be waterproof for the right size cable are used. There is a hole on the top of the enclosure (sealed via rubber washer in the picture) for the whip antenna.
